Bonding in Haloalkanes 4. Reactions of Haloalkanes What are Haloalkanes? Haloalkanes are: Saturated organic compounds, Contain: Carbon, At least 1 Halogen Atom. Classifying Haloalkanes We can classify our Halogenoalkanes. This is done according to the number of alkyl groups attached to the C atom bonded to the halogen atom, Primary: 1 alkyl group. Secondary: 2 alkyl groups. Tertiary: 3 alkyl groups. Summary: Classifying Haloalkanes Bonding in Haloalkanes: Polar Bonds Carbon: 2.1, Halogens: Fluorine: 4.0, Chlorine: 3.0, Bromine: 2.8, Iodine: 2.5. As the difference in electronegativity is significant, the C-X bond is polar. The electrons in the covalent bond are held closer to the halogen atom. The bond is polar.
